The correct formula is: 1.5 x (N-1) +1 where N is the score on a 7 point scale.

If you are considering a single ordinal variable, determining the mode or median would be meaningful, but the mean or SD would not. Many researchers do consider likert-scale data to possess only ordinal qualities. However, leading research studies, for example in the marketing area, obtain measures such as means and standard deviations from likert-scale data. Indeed leading textbooks also follow this approach. One concern has been that the 'distances' between points on a likert scale are not equal, for example the 'distance' or 'difference' between a strongly disagree and disagree is not the same as the difference between disagree and neutral. A recent study discusses these issues, as well as demonstrating that data obtained from 5-point, 7-point and 10-point likert scales are approximately comparable in terms of mean score (once re-scaled) and various measures of variation and data shape.

You can readily convert data from a 5-point scale to a 10-point equivalent. The process is basically to anchor the end points of the scale you want to convert to the 10-point. So 1 stays as 1, 5 becomes 10. The points in between are converted like this: 2 becomes 3.25; 3 becomes 5.5; 4 becomes 7.75. Note that this assumes the data are "equal interval" (e.g. the distance between 1 and 2 is the same as between 2 and 3 on the scale). Many researchers are leery of this assumption but the leading texts on marketing research assume equal interval data for Likert-based data. A recent study in the International Journal of Market Research reported on an experiment where three groups of respondents gave answers on either a 5-point, 7-point or 10-point scale. After this re-scaling procedure, the three scales gave almost identical results. The study reference is: Dawes, John "Do Data Characteristics Change according to the Number of Scale Points Used ? An experiment using 5-point, 7-point and 10-point scales". International Journal of Market Research, Vol 50, 1, 2008.
To convert a score from a 7-point scale to a 10-point scale, you can use the formula: ( \text{New Score} = \left( \frac{\text{Old Score} - 1}{6} \right) \times 9 + 1 ). This formula first normalizes the 7-point score to a 0-1 range, then scales it to a 0-9 range, and finally shifts it to a 1-10 range. For example, a score of 4 on the 7-point scale would convert to approximately 6.5 on the 10-point scale.

To convert 0.7 into a fraction, place the 7 over 10 (0.7 is 7 tenths). It is 7/10.
7 over 10 or 7/10
To convert a 10-point scale to a 5-point scale, you can simply divide the 10-point score by 2. For example, a score of 8 out of 10 would convert to a score of 4 out of 5. Alternatively, you can use a mapping system, where scores are grouped (e.g., 1-2 = 1, 3-4 = 2, 5-6 = 3, 7-8 = 4, 9-10 = 5). This ensures a clear and consistent conversion between the two scales.
7 _ 10
7 * 9.5
1.25*107
If you mean: 4.265*10^-7 then it is 0.0000004265
7 over 10 is the rational number 7/10 which is read as seven tenths. It can be convert to a decimal by dividing the numerator by the denominator: 7/10 = 7 ÷ 10 = 0.7
